Veeam Backup & Replication offers two options for backup to the Object Storage:
1. Direct backup to Object Storage
2. Backup to Object Storage as a capacity tier in the Scale-out Backup Repository (SOBR).
Follow these steps to configure direct backup:
1. Add Object Storage Repository: In Veeam Backup & Replication, navigate to the backup infrastructure and add a new object storage repository, selecting S3 compatible and providing your IONOS Object Storage credentials. We recommend using the eu-central-3 region for Veeam backups.
2. Configure Backup Jobs: Set up or modify backup jobs to target the newly added IONOS Object Storage repository.
For more information, see Add Backup Repository.
SOBR in Veeam enables you to create a highly flexible and scalable backup storage solution by combining multiple storage resources into a single repository. It allows moving data from performance to capacity tiers automatically to optimize storage usage and cost.
Follow these steps to configure SOBR with Object Storage:
1. Create Performance Tier: Add your primary, fast storage devices (local or network) as the performance tier in Veeam Backup & Replication.
2. Add Capacity Tier: Integrate IONOS Object Storage as the capacity tier, allowing Veeam to offload older backup files to cost-effective object storage.
3. Policy Configuration: Configure policies to define how and when data should be moved between the performance and capacity tiers.
In Veeam 12, both Performance and Capacity Tiers support multiple buckets without any limit and apply to users as follows:
Existing users upgrading to v12 should consider setting up a new SOBR with multiple buckets, as Veeam does not redistribute existing VM backups across newly added buckets.
For new users planning to integrate IONOS Object Storage in the Capacity Tier with a traditional SOBR configuration, it is advisable to start with multiple buckets.
Veeam automatically allocates VM backups across these buckets. While adding new buckets is possible later as well, Veeam does not reallocate existing VM backups to these new buckets; only new VM backups will utilize them. Utilizing multiple buckets in the Capacity Tier removes the necessity for multiple SOBRs.

In May 2024, we introduced the eu-central-3 Object Storage region in Berlin, Germany. This region features contract-owned buckets, providing enhanced performance and resilience. Note that a new 92-character access key is required for this region.
To move a backup repository to the eu-central-3 region, follow these steps:
1. Create a new access key: Check your access key length in the Key Management. If it is 20 characters long, you need to create a new 92-character key compatible with all regions. For more information, see Generate a Key.
2. Create a new contract-owned bucket with an Object Lock: Create a new contract-owned bucket in the eu-central-3 region with Object Lock enabled. For more information, see Create a Bucket and refer to the "contract-owned buckets" section.
Note: Select the No default retention option as the mode for the Object Lock.
3. Set up Veeam storage optimization: To do so, follow the steps in Set up Veam storage optimization.
4. Create backup repository: Creta an Object Storage as an object repository in Veeam. To do so, follow the steps in Create Object Storage as an object repository in Veeam.

5. (Optional) If you want to benefit from better performance, follow the instructions to enable 8 MB blocks:
Open the Registry Editor.
Navigate to Computer\HKEY_LOCAL_MACHINE\SOFTWARE\Veeam\Veeam Backup and Replication
Add a new DWORD (32-bit) value named UIShowLegacyBlockSize.
Set the value of UIShowLegacyBlockSize to 1. Now, the 8 MB block option will be available in the interface.
To apply the new storage configuration as the default for all future backup jobs, click Save as Default at the bottom of the Advanced Settings screen. This will ensure the settings are automatically used for any new backup jobs created.
Result: The Veeam storage optimization is successfully set up.

Veeam Backup & Replication allows you to configure block sizes for each backup job, which can significantly impact deduplication efficiency and incremental backup size. By default, blocks are compressed, typically achieving a compression ratio of about 50%.
Smaller blocks can enhance deduplication; they increase the number of calls to the object storage, potentially affecting performance.
Larger blocks reduce the number of storage calls and can increase throughput to and from IONOS Object Storage, improving overall backup performance.
For optimal performance with IONOS Object Storage, we recommend using 8 MB blocks. These blocks are unavailable in the interface by default and must be enabled via a registry key by following these steps:
1. Open the Registry Editor.
2. Navigate to Computer\HKEY_LOCAL_MACHINE\SOFTWARE\Veeam\Veeam Backup and Replication.
3. Add a new DWORD (32-bit) value named UIShowLegacyBlockSize.
4. Set the value of UIShowLegacyBlockSize to 1.
Result: The 8 MB blocks are now available in the Veeam interface.
